通过对普矿两用自卸车货箱上边梁结构的改进,有效减轻或降低货箱上边梁在受到货物冲击时的损坏程度,延长货箱的使用寿命,减少车辆的维修次数,提升车辆的使用效率,为用户创造更大的财富。普矿两用自卸车通常用于矿山开采、土石方转运等恶劣工况,并采用挖掘机进行装载。挖掘机等机械化装载方式下,常常会发生货箱上边梁被落下来的块状货物瞬间冲击而损坏的 Through the improvement of the structure of the roof beam of the container of the MPU, it can effectively reduce or reduce the damage degree of the cargo box roof beam when it is impacted by the cargo, extend the service life of the container, reduce the maintenance times of the vehicles and enhance the use of the vehicles Efficiency, create more wealth for users. Pu mining dual-purpose dump truck is usually used for mining, earth and stone transport and other harsh conditions, and the use of excavators for loading. Excavators and other mechanized loading methods, often occur on the container side beams were lumpy goods falling instant impact and damage
